combine status and data in same column with graph

As Jeremy said, the number after the ::, is the number of data sets (lines)
per graph.
In the case of my example, we are generating a stack graph, of all CPU
usage, so it will only look useful if all the datasets are graphed. And we
run multiple databases per host. 100 is a number I chose, because we are
unlikely to exceed 100 databases.

However, if you set that to something sane, like 4 or 5, you will only see
4 or 5 lines per graph, and multiple graphs will appear if necessary.

Hi Asif

Have a look here.
https://wiki.xymonton.org/doku.php/monitors:db_cpu.ksh
This is an example of what I think you are trying to do.

Looking at your link. What is  db-cpu::100 means in GRAPHS ? I did not see
any thing in xymonserver.cfg man page to explain the ``:100'' after the
columnname

So essentially you are taking advantage of both status and data channel in
the same script like I started with.

I will revisit my initial approach, except I will make sure there is no
NCV like data, like Jeremy suggested,  when sending to status channel or it
screw up the rrd with garbage.

Thanks for the link.

 You might find that adjusting the TEST2RRD variable to include only

"columname" and not "columnname=ncv" might do the trick.  The man page for
xymond_rrd talks about the "ncv" part only being used for status messages.
 But this is a long-shot.

Looks like if I do not have  columnname=ncv it does not generate a rrd
file.

:-(

I did some clean up so nothing in MSG has NCV like data and I added the
NCV data in the <-- ... --> . It did create the rrd file with the correct
NCV keys, but values
are zeros. It is dropping the values for some reason? So I am almost
there if I can figure out why the values are not showing up.

Are the values you're reporting counter-type (that is, always
incrementing) or gauge-type?  If you're sending gauge data and it's being
treated as counter data, then you will often get mostly zeroes or NaN.  By
default, NCV data is expected to be DERIVE which is a type of counter.  If
you want to change to GAUGE, then you need to set NCV_columnname to
describe this:

NCV_columnname="foo:GAUGE,bar:GAUGE"

The other option would be using --extra-test and --extra-script and

parse the values from the status channel to generate rrd?

Perhaps.  These seem a lot trickier to use.

One thought I had about this was to setup "--extra-test" and
"--extra-script" on the status channel, to filter out the status messages
from xymond_rrd.  If you use "--extra-script=/bin/true" and
"--extra-test=columnname" then I think it will feed the data to "/bin/true"
instead of parsing it itself.  Of course "/bin/true" will produce no
output, and hence no data.

  I want the graph show up in the test page, so sending it to just
trends won't work, right?

Right.  It needs to be listed in TEST2RRD to show up in the test page.

Hmm, just noticed this in the doco:

"No graph on the status page, but OK on the trends page
Make sure you have *ncv* listed in the GRAPHS setting in
xymonserver.cfg. (Don't ask why - just take my word that it must be there).
"

Do you have "ncv" listed in GRAPHS?
